Carbohydrate content governs growth‐storage allocation during recovery from carbon depletion

open access: yesNew Phytologist, EarlyView.
Conceptual framework for competing hypotheses of growth‐storage carbon allocation during recovery from carbon limitation. Summary How plants prioritize carbon (C) allocation between growth and storage remains an outstanding question, limiting predictions of forest C cycling and ecosystem resilience following periods of C limitation. To address this gap,

Defoliation of Oaks [PDF]

open access: yesNature, 1922
IN view of the deplorable effect of repeated defoliation of oaks by the larvae of Tortrix viridana, as noted by Mr. E. W. Swanton in NATURE for August 19, p. 250, it may be useful to remind planters that there are two distinct races of British oak (Quercus robur, Linn.), to which some botanists have assigned specific rank as Q.

Recent plant photosynthate as a driver of ecological and evolutionary processes

open access: yesNew Phytologist, EarlyView.
Timeline of key eco‐evolutionary outcomes arising from belowground allocation of recent plant photosynthate from shoots. Summary Plants rapidly allocate carbon from photosynthesis belowground via root exudates and root‐associated microorganisms. Here we synthesise recent evidence of our understanding of the consequences of this ‘fast’ pathway of recent

Why be deciduous in a tropical savanna climate? Insights from leaf deployment, stem growth and sap flow dynamics

open access: yesNew Phytologist, EarlyView.
Stem increment, sap flow and leaf phenology. Summary Savannas are ecosystems with hot and wet summers and warm and dry winters. How and why savanna trees partition their physiological activity through this seasonal cycle is unknown; yet it is important to understand this temporal partitioning in order to anticipate how anthropogenic climatic change ...

Screening for Fall Armyworm (Spodoptera frugiperda J. E. Smith) Resistance in Early‐Maturing Tropical Maize Adapted to Sub‐Saharan Africa

open access: yesPlant Breeding, EarlyView.
ABSTRACT Fall armyworm (FAW) (Spodoptera frugiperda J. E. Smith) has emerged as a serious pest since 2016 in Africa, affecting the food security and livelihoods of millions of smallholder farmers, especially those growing maize. Native genetic resistance to FAW is essential for reducing yield loss.

Inflorescence Photosynthesis Determines Resource Allocation, Seed Production and Senescence in an Agricultural Weed

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Agricultural weeds typically combine high reproductive output with fast vegetative growth. Here we analyzed the processes that overcome a potential trade‐off between vegetative growth and reproduction in the weed Avena fatua. We determined photosynthetic function of inflorescences and analyzed the transcriptomes of individual inflorescence ...
